A b s t r a c tThis study investigated the floral biology and pollen quantity and quality of Campanula bononiensis L. (Campanulaceae), a protected species in Poland. Observations and measurements were made during the years 2007-2009 in natural phytocoenoses from the Festuco-Brometea class situated within the Lublin area, SE Poland. A considerable decrease (approx. 87%) in population density was observed. Significant variations both in the amount of pollen (18.5%-34.8 % of pollen in the total anther dry weight, i.e. 0.5-1.5 mg per 10 anthers) and in pollen viability (38.8-97.0%) were noted. Both a low amount of pollen and low pollen viability may reduce the reproductive success of individuals. The most frequent visiting insects were bees (Apoidea), including solitary bees 45.7%, honeybees 20.4%, and bumblebees 11.4%. Dipterans, coleopterans (weevils), lepidopterans and ants were also recorded, implying a strong impact of C. bononiensis on insect biodiversity within grasslands.

“…Similarly, small plant communities in agricultural landscape, i.e. baulks, mid-field woodlots and fallows, are important refuge areas for forage vegetation [33]. These habitats increase the floristic biodiversity of these areas and simultaneously provide multispecies forage beneficial for bee development.…”

A b s t r a c tThe aim of the study was to compile an inventory and determine the ecological characteristics of the spontaneous flora of the restored water reservoirs and their wet banks in the western part of Lublin in the years 1997-2013. The study objects are small reservoirs located at the UMCS Botanical Garden in the Czechówka River valley. These ponds are subjected to strong anthropogenic pressure. 68 plant species from 33 families and 58 genera were recorded in the flora of the ponds and their wet banks. An important feature of the described water bodies is the large proportion of native species (94% of the flora). Cryptophytes and hemicryptophytes as well as biological groups combining the features of hemicryptophytes and cryptophytes are the predominant life forms. Perennials account for 80% of the flora. The ponds and their wet banks are inhabited by 25 medicinal and 19 bee forage plants.

“…A disadvantage is that road and railway constructions cause a considerable loss of natural habitats [12] and impaired environment quality, i.e., they modify microclimatic and hydrological conditions and develop dispersal barriers to many terrestrial animals [13]. However, a growing body of evidence shows that linear structures may benefit rural areas by creating important zones for general diversity of fauna [2,14] and flora [15][16][17]. The ecological value of habitats along road verges and railway embankments for pollinators is related to a number of functions, i.e., sites for nesting, mating as well as food sources for larvae and adults [3,18,19].…”

In this study, we evaluated if railway embankments and road verges create refuge habitats for bee flora across agricultural landscape. The survey was conducted in 2009-2012, in the Lublin Province, SE Poland. Data on the bee forage flora were obtained while making floristic charts along 60 transect plots × 300 m, with a total length of 18 000 m, for each type of linear structure. Forage bee flora was compared with respect to species richness, diversity, and evenness indices. The canonical correspondence analysis (CCA) was used to characterize relationship between species composition and environmental variables. The bee forage species richness and abundance were significantly greater on railway embankments than on road verges. The composition of species varied considerably; the number of bee forage species common to both habitats was only approximately 38% in entire data set. Most good-value bee forage species were recorded along the embankments of railways with an intermediate traffic volume. Bee forage species diversity benefits from the location of habitat elements (forests or meadows), primarily if the distance is <50 m. The lack of dense patches of valuable bee forage species in the road verges was related to the high density of non-nectariferous graminoids. Our results demonstrate how the value of man-made areas in an agricultural ecosystem can vary with respect to floral resources across the landscape, suggesting that it is inappropriate to generalize about agricultural systems as a whole without first addressing differences among habitats.
